CAN-MAKING MACHINE.

Specification of Letters Patent.

Patented Oct. 7, 1919.

Application filed Kay 11, 1918. Serial 1T0. 238,845.

To all whom it may concern:

Be it known that I, AUoUsT LOKAN, a citizen of the United States ofAmerica, residing in Astoria, county of Clatsop, and State of Oregon,have invented certain new and useful Improvements in Ca -MakingMachines, of which the following is a specification.

This invention relates to a machine for making cans, and aims to provideimprovements therein.

The bodies of tin cans are now made upon a machine known as a bodymaker, and this machine (when the cans are to be of the sealed type)comprises a horn extension or solder horn, tubular can bodies pass fromthe" forming horn. The tubular can bodies pass along the solder horn,and while thereon have solder applied to the seam where the two ends ofthe body blank are joined.

Solder-horns, as usually made at the present time, are supported at ornear the end where the can bodies pass all the same, by a roller, thecan bodies, as they move along the solder-horn, passing between theroller and the solder-horn. As each can body passes between the rollerand solder-horn, there is a little bump or jar, due to the thickness ofthe tin of the can ies.

There are, at the present time, machines upon which can bodies areformed at very nearly the rate of 200 cans per minute. In the very nearfuture, it may be predicted, these machines will be operated at a speedof somewhat more than 200 bodies per minu-te. At such a rate of speedthe bumps or shocks occasioned by the can bodies passing between thesolder-horn and a roller support, become very considerable, and, infact, objectionable, inasmuch as these bumps or jars are suflici ent todetach or shake solder from the seams, and hence produce defective orleaky cans, rticularly where the solder is a. plied to t e seam at theunder side of the liorn, as is now generally the case. Such shocks arealso likely to cause crystallization or granulation of the solder incooling, with similar disadvantages.

The present invention provides an improved mechanism or combination,wherein the solder mechanism is located and operlargely ates at theunder side of the solder-horn,

and the solder-horn is supigrted in such' manner that bumps or shoe areavoided onto which the as the can bodies pass the support for thesolder-horn at or near its discharge end.

An embodiment of the invention is illusstrated in the accompanyingdrawings. In said drawings,- Figure 1 illustrates so much of a canmaking machine as is necessary to disclose the invention, the dischargeend of the solder-horn, the solder mechanism and the sup" A, A designatea series of tubular can bodies, which are advanced along the solderhornin any suitable manner.

2 designates the solder-horn support. The solder-horn support hasportions which bear successively upon the solder-horn at various pointslongitudinally thereof, in such a manner that the can bodies A may pass,without the can bodies being directly interposed between the solder-hornand t of the solder-horn support which to support. the solder-horn.

As shown in the embodiment illustrated, the support 2 comprises anendless chain 3, carrying spaced project-ions 4, preferably rollers, andthese projections or rollers 4, preferably bear upon the under side ofthe solder-horn 1, in a oove 5, formed therein. The projections 4flaring in the groove 5 in the under side of the solder-horn are ofadvantage in reventing lateral displacement of the solder-horn on thesupport 2.

The chain 3 runs over sprockets 6 and 7. The chain and sprockets areconveniently carried by a bracket 9, and means, such as a P is acting 90screw shaft 10, is preferably provided for.

raising and lowering the bracket 9. This adjustability of thesolder-horn support permlts of the support being brought into positlonto support solder-horns of diiferent diably provided for the bracket 9,these guides 7 passing through holes in the frame of the machine.

A slide-wa 14, is referably provided upon the brac et 9 for t eprojections 4 carried by the chain 3.

The bracket 9 is preferably provided with an adjustable part 15 fortaking up the slack in the chain 3, one of the sprockets, as thesgrocket 7, being mounted upon this ad'ustab e part 15.

he chain 3 may be driven in any suitable manner. As here shown, thesprocket 6 is fixed upon a shaft 16, which has thereon a sprocket 17.The sprocket 17 is 'driven by a chain 18, passing-over a sprocket 19whic is connected in any suitable manner, to a driven part or shaft ofthe machine. An idler sprocket 20 is provided, which provides for takingup slack in the chain 18, and also enables the chain to be tightened orloosened, as the bracket 9 is adjusted vertically by the screw shaft 10.

The s ace between the projections 4 is preferably greater than theheight of the maximum size can body which the machine is designed toform. The movement of the chain 3 and the feed of the canbody isarranged to be at the same rate.

30 designates the solder mechanism. The solder mechanism. is preferablylocated beneath the solder-horn 1, and it may conveniently comprise asolder tank or trough 31, and a roll 32, dipping in the molten so]- der,and rotated by any suitable means, such as a gear 33 and associatedtransmission.

In operation, formed can bodies A, with the seam at the under side, assalong the solder-horn 1. Over the solder roll 32 the can bodies passjust near enough to the film of li uid solder upon the solder roll, tobe wet thereby, the solder being thereby applied to the seam upon theycan body After assing the solder roll, excess so der may wiped from theseam, as is usual, b a. brush or wi r' 40. ence the can bo ies pass tothe scharge end of the solder-horn,

seam being avoided.

The invention may be embodied otherwise than herein illustrated andspecifically described. I

What I claim is a 1. A machine for making cans, comprising a solder-hornand means for supporting the same, said means comprising a slideparallel to the underside of the solderhorn, and spaced horn-supportingparts traveling along said slide and contacting with said horn at pointsbetween the space between two can bodies on the horn, whereby said hornis supported without said supports coming in contact with a can body or1ts edge, sald horn supporting parts being spaced at such intervals thattwo'at least thereof are constantly in supporting contact with saidborn.

2. A machine for making cans, comprising a solder-horn and means forsupporting the same, said means comprising a slide parallel to theunderside of the solder-horn, an endless chain, said chain havinghornsupporting projections thereon, said chain traveling along saidslide and said projections contacting with-said horn at points betweenthe s ace between two can bodies on the horn, w iereby said horn issupported without said supports comin in contact with a can body or itsedge, said horn suprting parts being spaced at such intervals iliat twoat least thereof are constantly in su porting contact with saidhorn.

n witness whereof I have hereunto signed my name.
